curl -O https://www.python.org/ftp/python/3.11.9/Python-3.11.9.tgz
tar -xf Python-3.11.9.tgz
cd Python-3.11.9
./configure --enable-optimizations
make -j$(nproc)
sudo make altinstall

Step 3: Verify Installation

python3.11 --version

Should return:

Python 3.11.9

✅ Done! You now have Python 3.11.9 installed on your system.

To confirm pip is installed, run:

pip --version

If not, install it with:

python -m ensurepip --upgrade
